The gay couple are both cute 
I know.
Even if I'm slightly annoyed with them. 
Why 
I'm just not used to those types of people, but like you said, it's normal, and I really hope they make it far. 
Edit: Now I just realized, I'm not annoyed with them, but rather I'm slightly annoyed with their relationship status, but seriously, they make a cute couple. 
Just curious what you mean by this? Do you mean your not usually used to / in the company of gays?
Personally, I know a couple of gays / lesbians, but only know them, and am not normally in the company of gays either, but I don't know why their relationship status would annoy you?
It's very normal for 2 people of the same sex to be in a relationship and in no way should annoy people.

EDIT: Also, did you feel similar towards all the other gay / lesbians that were on the race? I'm genuinely interested.
